Nasa astronauts back on earth after nine-months in space

After nine months in space, Nasa astronauts Butch Wilmore and Suni Williams have finally arrived back on Earth.

Their SpaceX capsule made a fast and fiery re-entry through the Earth's atmosphere before four parachutes opened to take them to a gentle splashdown off the coast of Florida, reports the BBC.

A pod of dolphins circled the craft.

After a recovery ship lifted it out of the water, the astronauts beamed and waved as they were helped out of the hatch, along with fellow crew members astronaut Nick Hague and cosmonaut Aleksandr Gorbunov.

"The crew's doing great," Steve Stich, manager, Nasa's Commercial Crew Program, said at a news conference.

It brings to an end a mission that was supposed to last for just eight days.

It was dramatically extended after the spacecraft Butch and Suni had used to travel to the International Space Station suffered technical problems.

"It is awesome to have crew 9 home, just a beautiful landing," said Joel Montalbano, deputy associate administrator, Nasa's Space Operations Mission Directorate.

Thanking the astronauts for their resilience and flexibility, he said SpaceX had been a "great partner".

The journey home took 17 hours.

The astronauts were helped on to a stretcher, which is standard practice after spending so long in the weightless environment.
